IBOOKBINDERS PERFORATING-MACHINE.

Specification of Letters Patent.

Patented Feb. 15, 1910.

Application filed July 13, 1908. Serial No. 443,333.

To all whom it may concern:

Be it known that I, CHARLES F. Molina, a citizen of the United States,residing in Athens, county of Athens, and State of Ohio, have invented anew and useful Improve ment in Bookbinders Perforating-\Iachines, ofwhich the following is a specification.

The object of my invention is to provide an automatic feed for the bitsof a perforating machine such as is used by book binders in perforatingbooks preparatory to binding them.

A. further object is to provide a means, in a perforating machine, ofwithdrawing and elevating the bits, after the perforations have beenmade, so that the bit carrying frame will be in readiness for anotheroperation and at the same time will be removed from the way of theoperator in binding the book already perforated or in taking it from themachine.

A further object is to provide such a means for withdrawing andelevating the bits that will not necessitate working the bits backwardand which may be easily and quickly operated.

A further object is to provide a support, for the forward hinged portionof the base of the assembly box, which may be easily and quicklywithdrawn so that the said end portion may be doubled back, forconvenience in binding the book after the perforations have been made.

Another object is to provide such a device in a simple, strong, durableand comparatively inexpensive construction.

My invention consists of certain details of construction hereinafter setforth, pointed out in my claims, and illustrated in the accompanyingdrawings, in which- Figure I shows a front elevation view of my improvedbinding and perforating machine; Fig. II shows a detail view of one ofthe swinging lugs which I employ as supports for the end portion of theassembly box; Fig. III shows a sectional view taken on the line 3-3 inFig. I; Fig. IV shows an enlarged detail view, in plan, of the swinginglug, lever, and plate which in combination form the support for the endpor' tion of the assembly box, said view being a section taken on theline 41*4: in Fig. I; Fig. V shows a side elevation of the same; and, FiVI shows a detail view of the plate I employ.

This invention may be considered as an imprmement to my perforating andbinding machine for which I filed an applica tion for a patent on the31st day of March, 1908, and which application is No. 424,359, and theparticular application of this improvement to the said device is toprovide a means for raising and lowering the bit carrying mechanism andfor operating the mechanism which supports the forward part of theassembly box when the same has been placed in the machine.

Referring to the accompanying drawings the reference numeral 10 is usedto indicate a bit carrying frame, of the class described in my priorapplication No. 4124,2359, said frame being slidably mounted, forvertical movement, in uprights 11 and 12 and the bits being rotateduniformly and simultaneously by the operation of a hand or beltwheel 13.

The numeral 14 indicates the bit driving shaft and all of the mechanismcontained in the frame 10 is so constructed as to cause the frame to becapable of an easy movement, up and down, within the uprights 11 and 12.The said uprights 11 and 12 each consists of two parallel members, asillustrated in the sectional view which has been numbered III, and it isbetween the two members of the uprights that the frame 10 is mounted.

Mounted at right angles, between the uprights 11 and 12 and near theirupper extremity is a shaft 15 designed for rotary movement within itsbearings.

The numerals 16 and 17 indicate gear wheels (the gear wheel 17 beingonly shown by the dotted lines in Fig. I) so mounted on the shaft 15 asto assume a position immediately inside of the uprights l1. and 12respectively.

The numeral 18 indicates a belt or hand wheel mounted on one end of theshaft 15 for the purpose of providing a means for rotating the saidshaft.

Projecting upwardly, from each side of the frame 10, and in line withthe gear wheels 16 and 17 respectively, are vertical racks 19 and 20respectively, said racks being provided with teeth on their forwardfaces, designed to mesh with and be operated by, the gear wheels 16 and17 respectively on the shaft 15.

The numeral 21 indicates a ratchet wheel rigidly secured to the shaft 15and the numeral 22 indicates a pawl, mounted to the as sea upper crossbar 28, of my machine, designed necessary to use an assembly box, inwhich to engage the said ratchet wheel. The ratchet wheel 21 and pawl 22are so constructed and arranged, with relation to each other, as topermit of an upward movement of the frame 10 but a downward movement isprohibited. However the pawl 22 is loosely mounted upon the cross bar 23and may be thrown back on the cross bar 23 so as to be out of engagementwith the ratchet wheel but the normal position of the said pawl is inengagement with the said ratchet wheel over which it is adapted to ride.

The racks 19 and 20 extend vertically upward from the frame 10, andimmediately inside of their respective uprights 11 and 12, and areretained in this alinement by the metal straps 2a and 25 as shown inFig. I, thus obviously causing no hindrance to the upward or downwardmovement of the said frame.

The machine for which my construction is designed is provided with apressure bar 26 and means for operating same, as shown.

In practical operation the book to be perforated and bound is placedwithin the machine and securely held by the pressure bar 26. Theoperator then throws the pawl 22 upward and backward and out ofengagement with the ratchet wheel 21 and, by operation of the hand wheel18, moves the frame 10 downwardly until the points of the bits rest uponthe book to be perforated. The hand wheel 13 is then operated thusrotating the bits and it is obvious that the feed of the bits will beautomatic, on account of the weight of the frame 10, all of which isapplied to the bits. If for any reason the weight of the frame 10 is notsufficient to provide the desired feed the operator can supplyadditional pressure by means of the hand wheel 18. hen the bits haveperformed their functions and made the perforations, they are withdrawntherefrom by a reverse movement of the hand wheel 18, which causes theracks l9 and 20 to move upwardly on the gear wheels 16 and 17respectively. It is obvious that by this means the bit carrying frame isquickly and easily moved upwardly out of engagement with the book whichhas just been perforated anu it is then held in position, by means ofthe pawl 22, for its next operation.

An experienced operator, becoming thoroughly acquainted. with the mannerin which my device should be operated, soon becomes so proficient thatby the combined manipulation. of the hand wheels 13 and 18 he can causeall of the bits to simultaneously make perforations in a book severalinches thick within the space of from ten to fifteen seconds. In factthe operation is so very speedy that this device may well be consideredas a rotary punch.

In combination with this machine it is the book to be perforated andbound is made up, said book remaining therein during the drilling orperforating process and also the binding process. The assembly boxshould not be removed from the machine after the book has beenperforated until the same has been bound and for that reason an assemblybox, provided with a forward base portion which is hinged is employed sothat the forward portion may be dropped downwardly and out of the wayfor the binding process. The assembly boxes which I employ are of theclass described in my prior application which was filed on the 31st dayof March, 1908, and is numbered 424,358, and also of the class which isdescribed in my application for a patent for a binding machine of evendate with this application and whose Serial Number is eraser. In thepresent machine it is necessary to provide a means for supporting theforward portion of the base on an even plane with the body of the base,when the assembly box is in the machine and while the perforations arebeing made. It is also necessary to provide a means for withdrawing thatsupport so that the forward portion of the box may drop downward so topermit of threading twine through the perforations. To this end I haveprovided, for my machine, a table 27 the forward edge of which is at apoint immediately in the rear of, and flush with, the rear member of theparallel uprights 11 and 12 respectively, and when the assembly box isin the machine the hinged portion is designed to be in line with, orslightly in advance of, said forward edge of said base. Between themembers of the uprights 11 and 12 respectively and immediately below theplane of the table 27, I have mounted swinging lugs 28 and 29respectively, said lugs being adapted for pivotal movement on theirbearings and each being of a sufficient length to project inwardlytoward each other, for a short distance beyond the uprights 11 and 12respectively, and also to project outwardly beyond their respectiveuprights, as fully illustrated in Fig. I. In that portion of the lugwhich extends outside of the uprights 11 and 12 respectively I haveprovided a longitudinal channel 30 which is designed to be engaged by alever 31 01 32 respectively, secured to their respective sides of themachine and by this means the lug is designed to be held rigidly in itsnormal position, at right angles to the uprights 11 and 12, as shown.Centrally located on the upper surface and at the inner extremity of thelugs 28 and 29 are raised portions, 33 and 34; re spectively, which aredesigned to be received by slots 35 and 36 in the ends of the bar 37which is designed to rest upon the lugs 28 and 29 in a horizontalposition and in line with the table 27, when the parts of my device areresting in their normal positions. When the book has been perforated theoperator pulls the levers 31 and 32 upwardly and the inner ends of thelugs 28 and 29 swing downwardly, from their pivotal hearings, on accountof the fact that their securing means has been withdrawn and the weightof the bar 37 forces them downwardly. The bar falls off of the lugs 28and 29 and rests upon the uprights 38 v and 39 respectively. The lugsare now completely out of the way because by their construction theirwidth is less than the width of the members forming the uprights it and12 respectively, and when they have been released they fall downward andassume positions between the members forming the uprights 11. and 12respectively. The operator then picks up the bar 37 and lays it asideand bends the forward hinged portion of the base of the assembly box,whichv is not shown in these drawings as this is not a part of thisapplication, downwardly so :it

will be out of the way for the binding.

After the book has been taken out of the machine the parts are thenreturned to their normal position so that; they will again be ready foroperation.

Having thus described my invention what I claim and desire to secure byLetters Patent of the United States is:
